The .slittingmechanism, together with the winding.mechanism presently to be iay 4be driven frein any desired source or in .an inoperative posipower by any suitable means (not shown),

and saidslitting.mechanism (Figs. 1 and 8 y to 11) preferably comprises a shaft 11 jour naled in suitable bearings on the machine framework and having rigidly secured theretoatdesired intervals a plurality of Circular slitters, one of which is indioated aft/12;` These slitters are positionedonshaft 11v between eollars 12, 12 and serve to out web 8 into a plurality of narrower webs 8', 8, andifor this purpose the web 8 is passed under a roller 113 journaled` on trame piece 10 and then between the slitters and a Said'board is pivotallyv mounted on the ma? chine so that', before thesameis started, the boardniaybe turned downwardly fromthe slitters to theposition shown in dotted'lines. Fig.`8,rte permit vthe web to lie-freely passed to a d secured on .the .winding mechanism by an attendant. i' i Reierringuto Figs. 1, 2 and 7, the slitterboard :14 mounted ibetween spaced clamps 152, 1,5,-rigrdly secured on a shaft 16, eaehend or which is journaled in a suitablebearing' onan ,arm A16 of. a pedestal 16"..whioh'con-E st itutes a part of ythe machine vframew ork. f Suitable `iastening;*means may be -employed.

to securely hold the clamps .in engagement after passing through thev J described v slitter-.boardfl-fl.

, with the board as for example bolts which eX- tend through the clamps and board, one of.

said bolts being indicated at 17. A handle` 18 yis rigidly secured as by a key 19 on a pro- Y jecting end of shaft 16, and Vwhen the handle `tension 21 of pedestal arm 16 and byV a pawl 22 pivotally mounted at 23 in said extension. As shown in Fig. 7, stop pin is engaged by a shoulder-24 of a collar 25 rigidly secured on shaft 16, the shoulder and pin preventing further movement of the board to the left after it reaches` the full line position of Fig. 7. The p'awl22 engages a shoulder 26 of collar 25 and locks the board in its operative position. One end of a spring 27 is engaged over a lug 28 formed on the left end of pawl 22, the opposite extremity of said spring Vbearing against a lippedbracket 29 secured then engages pin 20 which thus serves as a Y by a bolt 30 to the pedestal arm 16. By depressing the pawl Aagainst the tension of spring 27, the` slitter-board can beV turned to the right through the mediumof handle 18, thereby moving the board and web 8 out of contact with the slitters. V The shoulder 26 stop for the board in its inoperative position.

The slitters are provided with a* guard (Figs. 8 and 11) consisting of a guard plate 31 for each slitter blade 12, said plate hav-V ing an elongated slot 32v through which the slitter bladenormally projects. The plate 31 is supported on strips 33,33 suitably secured as by riverts 34, 34 to L-bars 35, 35 which thus appearthat, while the spreader vbar and constitute part of the slitterguard` frame. Spacing pieces 36, 36 are interposed between said strips and then the L-bars, and the 'ends of each plate 3,1Y are engaged under L-bars 35, and secured between the latter and strips `33,33 by brackets 37, 37'riveted at 38, 38 to the Vv plate 31 and having set-screws 39, 39Y which maybe turned down into engagement j with horizontal flanges of L-bars 35, 35. The

Slitter guardframe further includes an L- bar 40 at each end thereof, and said frame is pivotally mounted'at 41 onfa bracket 42se cured to a crossstrut43, preferably 'made of 1 wood and constituting partv of the machine p ce framework. The pivotal connection for the 4slitter guard frame with'cross-strut 43 fun ther includes strap hinges, one of which is mdicated at 44 Fig. 8) the same being riveted at 45, 45 to the under side of L-bar 40.

.The head. 46o`fabolt 47serves as a stop V'for the slitter guard vwhen the slitter bar isV turned to its inoperative position indicated' bydotted lines, in Fig. 8. Said bolt passes through a suitable aperture in the slitter guard frame and is secured by nuts 48 and 49in a bracketed `extension 50 of the machine i framework. It will thus appear that when the slitter-board is returned to its inoperative position, the slitter guard will drop below the edges of the slitter blades and into engagement with the head 46 of bolt 47. Vl"he web 8 can then be passed by an attendant into the machine without the danger of his hands or the web coming into contact with the slit-f ters. Vhen theslitter-board is turned up to lift the web into contact with the slitte'r blade, said board raises the slitter guard to the full vline position of Fig. 8 and supports the same in such position while the web is being slit into the plurality of narrower webs 8', 8. Sidewise movement or displacement of the web with respect to the slitterboard Vis pre vented by aV guard 51 at each end of the board, said guard being secured tothe board by any suitable fastening means such as a bolt 52 and nuts 53, 54. AccordingA tothe present invention, suitable means are employed for spreading the web vor webs of material vertically as the same pass from the slitting mechanism to the winding mechanism. Said spreading means preferably comprisesa pluralityof spreader bars 55, 55, one for each of the several webs 8', 8 (Figs. 2 and 8). Each. bar 55 is provided longitudinally thereof with a suitable groove receiving a strip .56 of'ste'el or other material which contacts with .the adjacent web 8', and centrally of the ,bar is a suitable opening which receives` the head 57 and vsquared shank 58 of a spreader bar operatyconfiguuration in a flanged collar 60 secured by screws 61, 61 to thecross-strut 43.` It will its operating shaft may be moved vertically, the same arek prevented yfrom rotating by V reason ofthe squared lit between the shank 58 andthe collar 60. The spreader bar operating shafts extend vertically through suit able spacedv openings of the cross-strut 43, the threaded part 59 ofeachshaft extending through an opening in a flanged collar 62 secured tothe cross-strut as by screws 63,- 63.

Each spreader bar operating 2shaft is pro- Vvided with a handwwheel-64 threaded ,thereon'and by means of which the .barV` can be raised and lowered through the turning movement of said wheel. It will thus appear that the several spreader bars `can be moved vertically to different positions with respect t o each other and that the several webs 8. 8 will be separated or. 'spreadapartvertically from the point at which web 8 is slit to the mechanism on which the webs 8, 8*v `are wound.` 1 Spreading of the webs in the VInanner indicated prevents interference between the webs and interlocking of the ends of individual rolls wound therefrom to form a lilo Agrip and .release the Winder bar.

large ro'll 70 in a The Winding mechanism vof thepresent invention (Figs. l, 2 andl 4 to 6) includes a Winder bai Which'is introduced into the machine Aon one side thereof through the medium of a carriage 66.- Said carriage vis arranged for movement transversely of the mach-ine along a track 67, and for this purpose Vthe carriage is provided with a grooved roller 68 'Which engages the Atraclfand is prevented from displacement by a guard 69. In order to start roll 70, the slitter-board l/l is turned doWn and Web 8 is -passed by an attendant through the machine Over a Winding drum 71, rotating in the -direction Vof Jthe arroW (Fig. l). The Winder bar is 'then dropped-frein its `cai'rriage into supporting means adjacent the drinn so that the Winder bar rests on the Web and drum. The free end of the Web is then turned onto fthe Winder bar and the roll started by rotation of the drum 7l. Passing of the Web can be performed While 'the machine is in operation and after the roll 70 is started the slitter-board is raised, thereby lifting thevWeb into contact- With cutters 12 Which sever Web 8 into Webs 8', 8. The spreader bars are then loW- ered into engagement With Webs 8, 8 at different positions so that the Webs Will be spread as yabove described. rEhe roll 70 is thus constituted `by a plurality of individual smaller rolls Wound in end to end relation on bar 65. e i y Drum 7l is mounted on a shaft 72, each end of Which is journaled in a suitabie bearing 73, secured to a frame piece 74 ofvv the machine. The means for supportingthe Winding bar 65 in operative relation With `drum 7l 'preferably comprises snf'ingingf supporting arms disposed one ateach side of the machine and arranged for m vement so that the roll 70 and its contained Winderbfar may be caused to travel over the surface of Tinding drum 7l between the full and dotted line positions of the roll indicated respectively at A and C V(Fig. l). Said arms are prOvidedWith suitable mechanism for moving the same in the manner' above indicated and are further equipped With devices Which automatically Since't'he construction of the Winder bar 4supporting arms, the means formoving the same, and the associated gripping and releasing devices are identical at both sides of the machine, it is only necessary to describe the mechanism lo'- cated adjacent one side thereof. Each arm 75 includes large split collar the loiver part thereof, a bifnrcated upper entrerv ity providing aW portions 77, 7;, and a segmental gear 78 formed in or secured to a Weblike part of the arm. The armV 75' is rigidly secured on shaft 72 adjacent one extremity thereof'through the medium of collar 76 and set-screws threaded into suitable bosses on the split collar sections. One of these set-screws and the corresponding bosses are indicated respectively at 79 and 7 9, 7 9 in Figa. The segmental gear 78 engages'a pinion 80 rigidly secured on ashaft 81 extending transversely of the machine and j ouri'ialed in suitable bear- 1ngs,oneo'f Which is indicated atv 82. Bearing `82is formed on Aarm 16 and the shaft 81 projects outwardly through said `bearing and has secured thereon a ratchet 83' and hand- Wheel 84. The hand-Wheel serves to rotate the shaft 81 Which, through the medium of pinion and segmental gear 78 rotates the arm 75 `so `that roll 7 O may be moved over the surface of drum 7l as above described. A paWl 85, pivoted at 86 on the bearing 82, serves to prevent backward movement of the arn'i 75 and vthe roll 70 When the tivo are being moved, for example, from the initial ,Wind ing position A to the intermediate and final positions yindicated respectively `at B randfC. Said paWl is manually released to permit movement of the arms from position C to position A iin order to starte 'new roll.

A't each endthe'ivinder bar 65 has poi-'tions 87 and '88 of vrelatively different diameters, and When the Winder bar is dropped into its suppdrtingarnis 75 :between jaw portions 7 '77, port-ion 87 initially vrests on the bottom 89 of the jaw provided by portions 77,77. A lever is fp'ivoted fat 91 in an offset portion or boss 92 formed on fone 'of the j'aW portions 77, and said lever is provided With a.y pa-Wfl93. lVhen the Winderbar is dropped into place as` above described, the extension 88 trip's'lever 90 thereby disengaging the paWl y frein a ratchet 94 located at oneside ofthe jaw 77, 77 and ysecured as by a key 95 on a 'shaft 96` journa'led in a suitable bearing in boss 92.'. A lever 97 isrigi'dly securedtlo said shaft at the opposite side ofV the jaW. and when lever 90 Vis tripped and paWl 93 disengaged from ratehet'94, lever 97 is thrown from a substantially'vertical positionfinto engagement With eXtension 87 of the Winder bar lthrough the medium of a coiled spring 98, one end of which is engagedin a suitable aperture 99 formed in an offset portion 100 of lever 97. i

The opposite extremity of spring 98 is 'engaged vin the iapertured endof abolt 1011 threaded into a yboss 102 for'med on one of the sections of split collar 76,-sa-id bolt servi-ng to adjust the'te'nsion of spring 98 andbe'ing securedinits adjustedposition by means of @marea K The tension of spring 98 on lle'ver97 producesI a pressure ofthe latter on the Winder bar, Which tension and pressure serve, *particularly at thef time Winding of roll 70 is started, to produce -a uniform hard roll. As the roll 70 builds up at position A the Winder bar 65 gradually moves away from 'the surface' of 'roll 7l and raises lever 97 against the tensionV of sprilngf98 thereby moving `ratchet 9e in 'a vcounter-clockwise direction past pawl leb" lik)

When the roll 70 has been built up to a diameter of say approximately siX inches the same is moved from position A to position B yand then to position C by means of the supporting arm operating mechanism above described. Previous to thearrival ofroll 70 at i u mechanism adapted to accomplish this purposition C,.a hinged section`106vof a vertical guide 107 is lifted to the dotted line -position shown in Fi l, Where guide section 106 may be supporte by engaging a hook 108'With a pin 109 suitably secured on said section adjacent the free extremity thereon The lower part of guide 107 being opened, the end of the Winder baris received in said guide, the roll 70 then resting on ,Winding drum 71 and an auxiliary fluted Winding drum 110 rotated by any suitable means (not shown) at a surface speed corresponding to that of drum `71. Hook 108 is then disengaged from guide section 106 and the latter allowed to drop downwardly to the full line position shown 'in Fig.` 1,the guide section 106Y being maintained in its closed position by a detent 111 which en- Vgagespin 109.` The, auxiliary Winding .drum

110 is mounted on a shaft 112theend of which is journale'd in asuitable bearing 113 mounted on a `'pedestal 114 constituting lpart of the machine framework. The pedestal 114 also serves as a supportora verticalframe piece 115lonwhichthe frame piece 10 is bolt- Rotation of roll 70.by drums A builds said rolls upto the desiredsize," indicated for example by the large dotted circle at the left of Fig. 1, and causes the Winder bar tolift or move lever 97 to one side of the jaws Y77, 77 of the Winder bar supporting arm where, after the Winder bar has passed outrof 4the jaws, saidlever is retained and prevented from snapping back past sadjawsby the pawl 93 and ratchetV 94. The Winder bar supporting arm is then returned toposition A b'y rotating hand-wheel 84 and an empty Winder passed intoithe machine, through the mediumof carriage 66, for association with the :Winder bar supporting arm and the startingo a new roll.

The Winder, bar containedwithin the roll'.V` `Winding'at position C, gradually rises Within` `guide 107` which serves lto maintain said roll 'in properposition with respect to drums 71 and 110. y i I size, kthe splitter-board is lowered and the spreader bars raised.

ered from the roll between the slitting and `winding mechanisms so as to leave a free end extending over Winding ldrum 71. The empty winding bar is then dropped onto the web and drum and the bar engaged with the supporting arms as previously described. rlhe free end of the web is then` passed around said bar to start the new roll. The Winding operation again proceeds atv position A and the slitter-board is raised and the spreader barsvlowered so that the web forming the new roll is severed and the portions thereof spread vertically as the material is beingwound on the second bar.
